Hello, is it normal that it is not mentioned in the contract food/Transportation? It is also not mention holidays.
Is it required from the employer to pay for accidents health insurance? I couldn't find a template in English and the link for looking for salaries is not working anymore.

I'll be happy if someone can help regarding what I should be aware from.

Thanks!

Difficult to say without knowing what the job is, but if nothing is mentioned in the contract then I think the Federal/cantonal rules apply for holidays. Food and transport, don't think there's any obligation to provide these.

If you work more than 8 hours a week an employer has to provide accident insurance cover.

Theres a Swiss working law rule book, forget the name. This overrules anything in the contract that may contradict it. It is also the law, so the company may choose not to include specific clause as in affect they are taken for granted.

Then some industries sign up to a CBA, collective bargaining agreement. This is like a union and certain conditions will again be set out there which the employer will be obliged to follow.

However in your case, I expect there is a supliment document to your contract. The contract may be very basic, but there will be kind of a general terms and conditions. These will have working hours, holidays, time and attendance. It may mention insurance.

Unless you have a special condition it is unlikely you will get support or provisions for transport or meals. That said the additional document may give conditions for meals and transport if working away on business.

OR (Obligationenrecht)?

Give us some more info on type of job/employer etc.
Not mentioning holiday entitlement would ring alarm bells for me.

Note: if it’s anything to do with being a nanny, you need to be very clear on the contract to avoid becoming a modern day slave, for want of a better phrase.

To be fair, if they just follow the law there is no need to put it in a contract. There is a lot of stuff not in contracts due to the law covering it already. (else contracts would be hundreds of pages)

Fair comment, but many places do bridging days, or periodical shutdowns.
If the OP is a nanny, and the family insist on synchronized holidays or what not, they need to know up front, not be surprised by it.

The contract might point to the company rules which OP has not read yet.

If she indeed is a nanny, she'd better have a talk with her employer to settle things and get clarity.
